Helicobacter pylori strain ZH15 72

Helicobacter pylori strain ZH15 72 is a Gram-negative bacterium characterized by its microaerophilic oxygen requirement and spiral shape (spirilla). This strain is notable for its presence in various hosts, including Homo sapiens, Gallus gallus, Aves, Primates, Mammalia, Amoeba, Rodentia, and Cricetinae. It exhibits a free-living biotic relationship and is primarily associated with the gastric environment, where it can induce significant health effects. Notably, H. pylori strain ZH15 72 is linked to several gastrointestinal disorders, including chronic gastric inflammation, gastric ulcers, and various forms of gastric cancer, such as gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. Other health effects attributed to this strain include peptic ulcer disease, gastroesophageal reflux disease (GERD), and functional dyspepsia. The bacterium has the capacity to cause asymptomatic mucosal inflammatory responses, as well as more severe conditions like atrophic gastritis, dysplasia, and intestinal metaplasia. This strain's optimal growth temperature is 37°C, placing it within the mesophilic temperature range. It contains a single replicon and is encased by two membranes, consistent with the structure of Gram-negative bacteria. The presence of flagella allows for mobility, although specific mobility characteristics are not detailed. In summary, H. pylori strain ZH15 72's association with a wide range of hosts and its pathogenic potential underscores its ecological significance in human health and disease, particularly in the context of chronic gastrointestinal conditions and cancer development.
